LAME MT MP3 Encoding & Quake 4 Low Res.

In our custom LAME MT MP3 encoding test, we converted a large WAV file to the MP3 format. In this test, we created our own 223MB WAV file (a never-ending Grateful Dead jam) and converted it to the MP3 format using the multi-thread capable LAME MT application in single and multi-thread modes.

Converting a Large WAV To MP3

Processing times are recorded below. Once again, shorter times equate to better performance.

With our LAME MT testing, we saw both processors compete on the same level, with a mere one second difference noted in Multi-Thread testing, which does equal a 2% difference and is consistent with several variations previously reported.

Performance Comparisons with Quake 4

OpenGL

Quake 4

id Software, in conjunction with developer Raven, recently released the latest addition to the wildly popular Quake franchise, Quake 4. Quake 4 is based upon an updated and slightly modified version of the Doom 3 engine, and as such performance characteristics between the two titles are very similar. Like Doom 3, Quake 4 is also an OpenGL game that uses extremely high-detailed textures and a ton of dynamic lighting and shadows, but unlike Doom3, Quake 4 features some outdoor environments as well. We ran this Quake 4 benchmark using a custom timedemo with the game set to its "Low-Quality" mode at a resolution of 640 x 480 with AA and aniso disabled.

In our final test, we used our custom Quake 4 demo to assess subsystem performance by setting the resolution to 640x480 and the image quality to low. The end result was the "Windsor" core offering 3 FPS more than the "Brisbane", a lead of 3.48%.
